Serum tumor markers, including α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP), are currently used in the diagnosis of hepatocellular carcinoma (HCC). There is, however, an aberrant increase in serum DCP in patients with obstructive jaundice, vitamin K deficiency or who are

A 78-year-old man was admitted for workup for a liver tumor. Both serum AFP and PIVKA-II levels were high (2260ng/ml and 806mAU/ml, respectively). Contrast-enhanced CT scan and MRI using Gd-EOB-DTPA demonstrated a liver tumor in segment 6 resembling the imaging

Although the protein-induced vitamin K absence or antagonist-II (PIVKA-II) is used as a prognostic marker in hepatocellular carcinoma (HCC), a newly-improved assay, NX-PVKA (PIVKA-II measured using P-11 and P-16 antibodies) and NX-PVKA-R (ratio of PIVKA-II and NX-PVKA), are more accurate
